CodeToGo has now been used to run over one MILLION programs!

Write and run code in your favorite programming language, using your iOS device! Supports all iOS devices.

Just pick your language, write some code (with syntax highlighting for the most common languages), and run it. Each language has its own example "Hello World!" program for you to test.

CodeToGo gives you an API around ideone.com, allowing you to run code in many different programming languages (on a Linux server) and get the results back.

IMPORTANT NOTE: Unfortunately, because you can't actually run code on the iPhone, you MUST have an internet connection to run the code! You can however write, save, and load code without a connection.

INPUT: CodeToGo also supports supplying input (ahead of time) for your program - Just hit the "Input (stdin)" tab to set the user input (separating each different input with a new line), then hit the code tab to go back to writing code.

Save and load your code - The current code for a given language is automatically saved for you, and you can also save and later load different files for each language. You can also save and load files from Dropbox, or transfer to and from your computer with iTunes File Sharing.

For faster programming, CodeToGo even adds an extra row of commonly used keys to the default keyboard. You can also customize this extra row by touching the "Settings" button at the top right of the initial language screen.

If you need to jump to a specific line in your program (the location of an error, perhaps), you can do that too! The "Goto line" button lets you type in a line number and jump to it.

And if you're doing web development, you can render the output of your program as HTML! After running your program, just hit the "Render as HTML" button to see what it would look like on a web page.

5/5 stars


Considering apple won't allow a compiler to run directly on the iPhone/iPad, this is a wonderful "work-around". The languages available are an added bonus. This is a great app for writing and testing code bites and algorithms. Bravo !!

3/5 stars

Good for basic needs

Great if your are writing SUPER basic code like hello world, but it lacks a user interface that allows input during runs.

3/5 stars


I am new in writing codes, needed a way to use them on my iPad but I just started learning objective-c, and it is not listed among the languages. I thought "small talk" was similar to obj-c but I could not get it to work. I am not proficient in any other languages, if you can add it that will be nice other than that I think it is ok.
